In 2006, Elvira Arellano took refuge with her 7-year-old son inside Adalberto United Methodist Church in Humboldt Park. Arrested four years earlier as part of a post-9/11 sweep of immigrants who were in the U.S. illegally, Arellano became the face of the new sanctuary movement. She was arrested and deported in 2007 after leaving the church, but returned in 2014 and has applied for protected status. She is now again living in Humboldt Park.
